    Posted this in the other thread but I didn't want it to get glossed over. Some info from Matthew Polk regarding the Bass Brace:

    Tony –

    The “Bass-Brace” was introduced as a recommended modification for the SRS 1.2 and was available free for the asking. The kit was composed of nothing more than a piece of all-thread, ?” I think, with a t-nut for the back of the cabinet and an selection of wall anchors. All late production SRS models came with the t-nut already installed in the back of the cabinet plugged with a bolt to seal the hole. (Note: when the all-thread is screwed into the cabinet it will often wind Dacron around it like cotton candy jamming in place and requiring removal of a driver to free-up.)



    The “Bass-Brace” did make a noticeable difference in bass performance. Slam and speed were noticeably improved. If you anchored to a masonry wall the difference was really quite dramatic, more than you’d get from improving your speaker cables and even better than spikes.



    However, the real reason for the Bass-Brace was not initially to improve performance. Around that time new industry safety guidelines were issued for loudspeakers which included a “tip test”. The tip test specified that with the speaker placed on an inclined plane at 10 deg. (as best I recall) it would not tip over in any orientation. Needless to say, the SRS products did not pass. That was a real problem and with an inventory of product already in the warehouse we needed a solution. The solution was the Bass-Brace which when installed prevents the speaker from tipping over. But, when trying it out we realized it also made a significant performance improvement. So, it became both a performance modification and a safety feature. However, it was very difficult to install and I doubt many SRS owners ever enjoyed the benefits. Over Amy’s objections I did install mine and anchored them to an 18” thick brick and masonry wall. It was very impressive.



    Hope that helps



    -msp


    Cheers.

    When I bought my SDA 2B Studios back in 1988, the salesman gave me a pamphlet that detailed how the salespeople were supposed to demonstrate the SDA's. A lot of it was positioning of the speakers and is covered under the owner's manual. It also included 3 pages of songs to demonstrate the abilities of the SDA's. The guy said they normally didn't give out this pamphlet. I'll send it to you tonight/tomorrow and you can look it over and see if you want to post it under other information.

    You know I see all these SDA ads and reviews selling on Ebay for like $10
    I wish we had a place to put every old ad and review in one place.

    Trey, can you add the "bass brace" mod that Raife did for his 1.2TL's and/or SRS's please? I didn't see it on your page, and others may like to read up on how Raife did it. Thanks Trey.
